John's Gospel makes a big point that changing water into wine at a wedding feast was the first miracle Jesus worked. But John called it a "sign" instead of a miracle. And that in itself is significant. What did this miracle point to? What is the significance that this miracle took place at a wedding feast? Although perhaps a minor point, that Jesus was no cosmic killjoy because he provided wine to gladden the feast, the point would seem to be far more than that. It pointed to Jesus' unique identity and what it is that he was accomplishing for us.
